Toxoplasma gondii: Cloning, expression and immunoreactivity of recombinant ROP5 and ROP18 antigens

- We generated five recombinant forms of Toxoplasma gondii ROP5 and ROP18 in E. coli.
- Recombinant ROP5 and ROP18 were recognized by the sera of T. gondii-infected mice.
- Anti-ROP IgM antibodies seem to be an early and sensitive marker of toxoplasmosis.
